Christ wants to live His life through us.
He wants to use our eyes to behold the world situation as it is today. He wants to use our ears to hear the cry of the unsaved and the cry of those who are in need. He wants to use our lips to tell others the Gospel.
He wants to use our hearts to express compassion and love to everyone. He wants to use our minds to think through situations and to have something to say to the people involved. He wants to use our hands to do His work and our feet to get to the places He wants to go to help others through us.
The body also includes the soul, which is the seat of the intellect, the emotions and the will. God not only wants the physical aspect of our bodies, but He also wants our intellect, emotions and will.
Christ wants to think His thoughts through us, and He wants to bring our minds under His control.
Second Corinthians 10:4,5 says, "(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ."
Jesus Christ also wants our emotions so He might express Himself through us to a lost and dying world. The Lord Jesus Christ also wants our wills through which to make decisions that will honor Him.
"For as many of you as have been baptized into Christ have put on Christ" (Gal. 3:27).
